Sweet Potato Latte is soooo tasty!!!!! There is this really good cafe called, "YakiniQ" in Japantown San Francisco and they are the ones that created this drink. They also sell delicious macarons, too! Sweet potatoes have a good amount of fiber and soy milk is high in protein. This drink will definitely make you full after you drink it! Just make sure to use the dark skinned sweet potatoes because they are sweeter.
